4.3. Calibrating the Full Scales
After checking the zero settings you may then calibrate the full scales. Set the digit switch to
’999999’.
Adjust the 1V Full Scale with the ’CAL’ trimmer which is on the potted module.
Adjust this to read 1V to within 20uV.
Adjust the 10V F.S. trimmer, VR5, to read 10V to /- 200uV.
Adjust the 100mV & 10mV F.S. trimmer VR3, to read 100mV to / - 4.3µV
(Done on 100mV Range)
Check 10mV F.S. is within 1.3µV.
Adjust the 100V F.S. trimmer, VR6, to read 100V to /- 3.5mV.
Adjust the 100mA F.S. trimmer, VR7, to read 100mA to /- 6uA.
4.4. Calibrating the Deviation Control
Set the output to the 1V on the 1V range and set the deviation to +0.999%. Adjust the output
using the + Deviation trimmer, VR9, to read 1.01V to within 5mV.
Leaving the output at 1V on the 1V range, set the deviation to –0.999%. Adjust the output
using the – Deviation trimmer, VR8, to read 0.99V to within 5mV.
The Calibration procedure is now complete.
